Rtg-Tag-List

This field contains a comma-separated list of routing tags that are accepted by this interface. If this list is empty, then all routes are accepted irrespective of their routing tags. If the list contains at least one tag, then only the tags in this list are accepted. Similarly, when marked routes are being sent, only routes with permitted tags (i.e. those listed here) are forwarded. The routing tag list corresponds insofar to the WAN RIP list with the difference that any realization using standard routing is also taken into account. This means for example that, in the case of an interface tag '1' and the standard routing tag '0', the tag '0' has to be included in the routing tag list because it is internally changed to tag '1' when it is received. When transmitted, the internal tag '1' is converted into the external tag '0'. This measure is necessary in order for a virtualized router to be able to work together with other routers in the LAN that do not support tagged routes.
